Semyon Alexandrovich Ginzburg (1900–1943), attended the Dzerzhinsky Military Technical Academy in Leningrad. He worked in the GKB (the main design bureau) and in the KB-3 in Moscow. In 1930 he was a member of the Soviet purchasing committee in Great Britain that prepared buying a licence for the Vickers 6-Ton tanks, the basis for the T-26 Soviet tank.
Ginzburg then headed the experimental group preparing the production of the T-26 type. Later on he worked in Leningrad. He was directly involved in development of experimental types like T-33, T-43, T-29, T-46-5, T-100 and T-126SP, as well as in the series built T-26, T-28, T-35 and T-50 types. A deputy to Zh. Ya. Kotin, himself a deputy to the Minister of the tank industry, S. A. Ginzburg was directly responsible for development work of the SU-76 light self-propelled gun. The poor initial quality of this weapon was a reason for his removal from that position and sending to front. He became a chief technical officer of a tank corps. He died at the front in 1943.
